right this problem has been on going on my car... basically sometimes my car will boost ok (it's set up for 1.1 bar using a boost controller greedy profec)and then the next time it won't i've had the turbo rebuilt with a new housing by turbo dynamics,i've replaced all the silicone hose for my front mount,i've replaced the det sensor and i'm getting a codee 55 all clear, now when i run the car with the hose off the accuator it only goes up to 1.1 bar where i've been told it should basiclly go of the gauge,i've also unplugged the heat sensor from under my seat as well....any help/ideas would be graetly appreciated
